Omega DPF500 Series manual Typical Applications / Wiring Diagrams

2.4 Wiring

Several typical applications of the DPF500 are shown below. Please observe that the various pulse inputs and power options may be intermixed in many ways to solve common applications. The isolated pulse output may be freely used so long as proper polarity is observed.

Caution : When 4-20 mA loop option is provided, the power wiring to the loop power option should always be to terminals (+) 12 and (-) 11. Accidental wiring to (+) 12 and (-)6 should be avoided since excessive current fl ow may result.

Caution : The magnetic pickup input and contact closure input require isolated sensors for proper operation. Ac- cidental connections to earth may result in erroneous operation of the analog output and/or excessive current fl ow.

Caution : Accidental connections from circuit common (3 or 6) to earth or terminal (11) may result in erroneous op- eration of the analog output and/or excessive current fl ow.
